·  Use customary units of liquid volume.
·  Use metric units of liquid volume.
·  Measure and estimate weight and mass.
·  Solve word problems involving liquid volumes or masses using addition, subtraction, multiplication and division.
·  Tell and write time to the minute, quarter hour, half hour, and hour.
·  Tell and write the time before and after the hour to the nearest minute.
·  Find elapsed time.
·  Solve word problems involving addition and subtraction of time intervals in minutes and intervals of time.
·  Draw scaled pictographs and bar graphs and solve comparison problems using data in pictographs and bar graphs.
·  Analyze data to create horizontal and vertical bar graphs. / 3A: Tell and write time to the nearest interval. [3.MD.1]

3.MD.1: Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
3.MD.2: Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).6 Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.7
Represent and interpret data.
3.MD.3: Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
